THREE ARGUMENTS AGAINST FOUNDATIONALISM: ARBITRARINESS, EPISTEMIC REGRESS, AND EXISTENTIAL SUPPORT forthcoming in Canadian Journal of Philosophy Daniel Howard-Snyder and E.J. Coffman Abstract. Foundationalism is false; after all, foundational beliefs are arbitrary, they do not solve the epistemic regress problem, and they cannot exist without other (justified) beliefs. Or so some people say. In this essay, we assess some arguments based on such claims, arguments suggested in recent work by Peter Klein and Ernest Sosa. A particular belief of a person is basic just in case it is epistemically justified and it owes its justification to something other than her other beliefs or the interrelations of their contents; a person’s belief is nonbasic just in case it is epistemically justified but not basic. Traditional Foundationalism says that, first, if a human being has a nonbasic belief, then, at bottom, it owes its justification to at least one basic belief, and second, there are basic beliefs. Call the second thesis Minimal Foundationalism. In this essay, we assess three arguments against Minimal Foundationalism which we find in recent work of Peter Klein and Ernest Sosa.1 1. Foundationalism and Arbitrariness Peter Klein puts his case against Foundationalism succinctly as follows: [F]oundationalism is unacceptable because it advocates accepting an arbitrary reason at the base, that is, a reason for which there are no further reasons making it even slightly better to accept than any of its contraries. (Klein 1999, 297) The argument suggested here is plain enough: The Argument from Arbitrariness 1. If Foundationalism is true, then there are basic beliefs of the following kind: S’s basic belief that p is justified although there are no further reasons that make it even slightly better that S believe p rather than any of p’s contraries. 2. There can be no such beliefs. 3. So, Foundationalism is false. (1, 2) 1 Four notes in one. (1) Hereafter, we will leave the modifier “Minimal” in “Minimal Foundationalism” implicit. (2) We add “…or the interrelations of their contents” to the definition of basic belief to rule out Pure Coherentism as a version of Foundationalism. We leave this clause implicit in the text. (3) Epistemic statuses other than justification are amenable to the basic/nonbasic distinction, but to make this explicit would needlessly complicate the text. (4) Our definition of basic belief needs to be qualified; see note 3 and the text to which it is referenced. 1 A question arises: what sort of thing is a “reason,” according to Klein? As it turns out, Klein uses “reason” to refer both to beliefs, which are a certain sort of mental state, and to propositions, which are not.2 Let’s not worry about which Klein meant and consider both options. Suppose reasons are propositions. Then premise 1 reads: 1a. If Foundationalism is true, then there are basic beliefs of the following kind: S’s basic belief that p is justified although there are no further propositions that make it even slightly better that S believes p rather than any of p’s contraries. Unfortunately, 1a is false. There are versions of Foundationalism according to which there are further propositions the truth of which make it (at least) slightly better that S believes p rather than one of its contraries, even if S’s belief that p is basic and justified. To illustrate: suppose that Evan’s (allegedly) basic belief that the ball is red owes its justification to the ball’s looking red to him and not to any other beliefs of his. This supposition is compatible with a version of Foundationalism according to which Evan’s belief owes its justification to his visual experience because, in part, these two propositions are true: (A) When one’s belief that a ball is red is caused in normal circumstances by the ball’s looking red to one, it is very likely that the ball is red, much more likely than that the ball is yellow or blue, for example. (B) Evan’s belief that the ball is red was caused in normal circumstances by the ball’s looking red to him. So, on this version of Foundationalism, there are some further propositions, namely (A) and (B), the truth of which makes it (at least) slightly better that Evan believes the ball is red rather than, say, yellow or blue. Other versions of Foundationalism have the resources to make the same point, mutatis mutandis. Indeed, it’s difficult to think of one that lacks them; after all, each version of Foundationalism has some story to tell about how basic beliefs are justified and that story will consist of some propositions the truth of which would make it the case that for each basic belief that p, it is (at least) slightly better that the person who holds it believes that p rather than any of p’s contraries. Perhaps Klein’s line of thought will fare better if we take “reasons” to refer to beliefs. In that case, premise 1 of The Argument from Arbitrariness reads: 1b. If Foundationalism is true, then there are basic beliefs of the following kind: S’s basic belief that p is justified although there are no further beliefs that make it even slightly better that S believes p rather than any of p’s contraries. Is this an improvement? We think not. There are versions of Foundationalism according to which there are further beliefs the truth of which make it (at least) slightly better that S believes p rather than one of its contraries, even if S’s belief that p is basic and justified. To illustrate: consider Evan again, and suppose someone else, say William, correctly believes both (A) and (B). This supposition is compatible with a version of Foundationalism according to which Evan’s belief owes its justification to his visual experience because, in part, what William believes, namely 2 The paragraph straddling (Klein 1999, 298-99), uses 'reason' to denote a belief (where belief is a kind of mental state), while the very next paragraph uses 'reason' to denote a proposition. 2 (A) and (B), are both true. So on this version of Foundationalism, Evan’s belief can be basic even if there are some further beliefs—e.g., William’s belief that (A) and (B)—the truth of which makes it at least slightly better that Evan believes that the ball is red, rather than yellow or blue. No doubt, the same point can be made by other versions of Foundationalism, mutatis mutandis. Perhaps it matters whether Evan himself is the one who believes (A) and (B). If so, then Klein’s purposes might be better served by 1c. If Foundationalism is true, then there are basic beliefs of the following kind: S’s basic belief that p is justified although there are no further beliefs of S that make it even slightly better that S believe p rather than any of p’s contraries. Is this a change for the better? No; 1c is false. That’s because there are versions of Foundationalism, like the one sketched above, according to which S’s belief that p can be basic and justified even though there are further beliefs of S the truth of which makes it (at least) slightly better that S believes that p rather than one of its contraries. To illustrate: return to Evan, and suppose that he correctly believes both (A) and (B). That supposition does not imply that Evan’s belief that the ball is red is not basic. For the mere fact that Evan believes (A) and (B) does not imply that his belief that the ball is red owes its justification to those two beliefs of his. To suppose otherwise is to fail to distinguish two states of affairs: • Evan believes that the ball is red and Evan believes (A) and (B). • Evan’s belief that the ball is red owes its justification to his belief that (A) and (B). While the second implies the first, the first does not imply the second. Thus, so long as Evan’s belief that the ball is red does not owe its justification to his belief that (A) and (B), his belief that the ball is red might well be basic. Perhaps one will object: “But surely, if Evan believes (A) and (B), then his belief that (A) and (B) must be, at least in part, his grounds for his belief that the ball is red. In that case, Evan’s belief that the ball is red cannot be basic.” We deny both claims here. The first claim—that if Evan believes (A) and (B), then his belief that (A) and (B) must be, at least in part, his grounds for his belief that the ball is red— fails to distinguish two states of affairs: • Evan believes that the ball is red and Evan believes (A) and (B). • Evan’s belief that (A) and (B) is, in part, Evan’s grounds for believing that the ball is red. While the second implies the first, the first does not imply the second. That’s because, in general, one can believe the premises of an argument and yet not believe the conclusion on that basis but rather on the basis of something else. The second claim—that if Evan’s belief that (A) and (B) is, at least in part, his grounds for his belief that the ball is red, then the latter belief cannot be basic—is false. That’s because a basic belief can have multiple sources of justification; when it does, its epistemic status is overdetermined.
